While playing, I found some minor problems in the Yor Tech Tree.
1. Under Propagation, the "Industrial Specialization" tech lists the bonus "Manufacturing Cost -5%" twice. Not sure if this gives a total of -10% or if one of the bonuses is redundant.
2. Under Warfare, spelling of "Miniturization Specialization" is incorrect. Should be "Miniaturization"
3. Under Warfare, the "Point Defense Specialization" tech has description: "Increases strength of point defenses", but the actual bonus is "Point Defense Cost -10%". I'm not sure what the implementation actually is.
Thanks for your attention.
Edit: 4. Under Propagation, "Optimized Research" description is "Increase the Adjacency bonuses of Research Improvements", but the actual bonus is "Research +10%". Once I researched this and now see that the actual implementation is +10% Research with no additional adjacency bonus. So the error is in the description text.
Edit: 5. Under Warfare, "Focused Beam Weapons" description is "Increases damage of beam weapons". Bonus is "Beam Range +10%" and this bonus is listed twice.
Edit: 6. Under Warfare, "Kinetic Range Extention". Spelling error - should be "Extension". Also the bonus "Kinetic Range +20%" is listed twice.
